The past couple of weeks I am working with Silverlight controls embedded in SharePoint 2007.
For one of the controls, I need to retrieve the data using the Search Query Web Service.

This was working perfectly in the development environment. But when deploying the control to the production environment it did not work.

The problem

With the introduction of the August Cumulative Update for SharePoint 2007 (KB973399) we encountered System.NullReferenceException: Object reference not set to an instance of an object. on all pages inheriting from MySitePublicWebPartPage.

Stefan Goßner reminds us of the fact that support for WSS 3.0 SP1, SharePoint 2007 SP1 and Project Server SP1 will soon end.

I was having trouble with the clock in my Linux Hyper-V VMs. The time was constantly drifting forward. Using the Network Time Protocol (NTP) only slowed the drift a bit down but often the NTP-service gave up after several days.

I am running Linux in Hyper-V VMs since the launch of the Windows Server 2008 RTM. But in the beginning it was quite complex to get real performance and support for the network drivers.

Recently, with the launch of Windows Server 2008 R2, there are also new Linux Integration Components which also work for Windows Server 2008 RTM.
